IR Infrared 3 - 100cm Obstacle Detaction Sensor Module

RM20.00

The basic concept of IR(infrared) obstacle detection is to transmit the IR signal(radiation) in a direction and a signal is received at the IR receiver when the IR radiation bounces back from a surface of the object.

Move your hand towards the IR LEDs. As you near them, the Output LED on the module and the LED for pin 13 on your Arduino will illuminate. Open your serial monitor and vary the distance of your hand while viewing the serial monitor. The output should show "Clear" to "OBSTACLE!!, OBSTACLE!!".
